A followup to "How the Top 50 Nonprofits Do Social Media". The top five nonprofits listed here in each category were ranked based on total expenses provided by Charity Navigator. Universities, hospitals, 501c4's and donor-advised funds are not included in the report. The numbers we have reported were rounded to the nearest whole number. During the week of October 26th 2011 we took these lists of the top five nonprofits and generated metrics to determine how different verticals were utilizing social media.
